*@Note
SPI DMA, master/slave mode transceiver routine:
Master:SPI1_SCK(PA5)\SPI1_MISO(PA6)\SPI1_MOSI(PA7).
Slave:SPI1_SCK(PA5)\SPI1_MISO(PA6)\SPI1_MOSI(PA7).
This example demonstrates that Master and Slave use DAM full-duplex transmission
and reception at the same time.
Note: The two boards download the Master and Slave programs respectively, and power
on at the same time.
Hardware connection:PA5 -- PA5
PA6 -- PA6
PA7 -- PA7
